ROBERT HENRY, OF BLUE LAKE, CALIFORNIA.

WIND OW-SASH FASTENER.

To all whom it may concern:

Be it known that I, ROBERT HENRY, a citizen of the United States, residing at Blue Lake, in the county of Humboldt and State of California, have invented a new and useful lVindow-Sash Fastener, of which the following is a specification.

This invention relates to window sash fasteners, and has especial reference to window sash fasteners which look the meeting rails of sashes together.

The invention has for its object to provide a window sash fastener of this kind, which will be simple in construction, easily operated, and will positively lock the window.

The invention consists in a Window sash fastener, constructed, and arranged as hereinafter described, and claimed.

Referring to the drawing, Figure 1 is a perspective view of a portion of the meeting rails of a window sash, showing the invention applied thereto. Fig. 2 is a side view, showing the meeting rails in cross section, and the sash fastener in locked position. Fig. 3 is a perspective view of a bolt and lever showing a modified form of connection between the two.

In the accompanying drawing, 1 is the meeting rail of the upper sash of a window, and 2 the meeting rail of the lower sash. Extending through the rail 2, is a passageway 3, formed at its forward end with a rectangular socket 4 in which is seated a rectangular casing 5, projecting from a metallic plate 6, let into the outer face of the rail 2, and secured thereto by screws or other fastening. Opposite the plate 6, is seated in the rail 1, a metallic plate 8, secured to the rail 1 and having a hole 10 in alinement with a socket 11, in the rail 1.

Extending through the passage-way 3, casing 5, hole 10, and projecting into socket 11, is a locking slidable bolt 12, which projects at its rear end through a hole 13 in a metallic plate 14, secured by screws 15 to the inner face of the rail 2. Upon the bolt 12 adjacent to its forward end is mounted a rectangular block 16 fitting in the rectangular casing 5, and slidable therein to guide and steady the bolt 12 in its movement. Mounted on the bolt 12 is a coiled spring 17 having its ends bearing against the block 16, and plate 14, and serving to hold the bolt in locked position as shown in Fig. 2, and to automatically throw the bolt into'locked position, when it is desired to lock the win- Specification of Letters Patent.

dows. To withdraw the bolt 12, from its locked position suitable means are provided therefor, and, as here shown preferably consisting of a lever 18, pivoted between its ends, on a suitable bracket 19, mounted on the inner face of the rail 2, and fastened at its inner end to the end of the bolt 12, projecting from plate 14. To hold the bolt 12 in retracted position, against the tension of coiled spring 17, a suitable locking device is provided for engaging the outer end of lever 18, and, as here shown, consisting of a button 20, mounted on the rail 2 and movable into and out of engagement with the tapering end 21 of the lever 18, and as shown in Fig. 1, holding the outer end of the lever 18 against the rail 2, with the bolt 12 in retracted position, and the spring 17 co1npressed. It will thus be seen that when it is desired to lock the window, by simply turning the button 20, and releasing lever 18, the bolt 12 will be automatically thrown, by the action of spring 17, to lock the window. A specific construction and arrangement of parts has been set forth but it is not intended to limit the invention thereto, as the parts may be differently constructed and arranged without departing from the essential features, and spirit of the invention.

In order to adapt the fastener to sashes of different thicknesses the lever and bolt may be adjustably connected together in any suitable manner, as for example, as shown in Fig. 3, in which a bolt 22 is employed provided on its outer end with notches 23, with which is adjustably connected the end of a lever 24 having a slot 25 engaging the notched end of bolt 22. In order that the lever 24 may be readily removed from a sash to adjust its connection with the bolt a suitable hinge is provided for the lever, as here shown, consisting of screw eyes 26, and a detachable pin 27 extending through the lever, and the screw eyes and secured by a nut 28 on the end of pin 27. By removing lever 24 it may be connected by means of its slotted end with any of the notches 23 thereby providing a length for the bolt from the end of lever 24 to the inner end of the bolt 22 which adapts the latter to the thickness of the sash through which it extends.

Having described the invention, I claim 1. An upper window sash having a bolt socket in its meeting rail and a plate with a hole in alinement with said socket; a lower sash having a passage way extending through its meeting rail with a socket at its forward end, and a guide casing in said socket; a plate with a hole at the rear end of said passageway; a slidable bolt extending through said passage way and through the holes in the said plates; a guide block mounted on the bolt and slidable in the guide casing a coiled spring on the bolt between said block and the inner plate retracting lever hinged to the lower meeting rail and connected to the bolt; and a locking device adapted to engage the outer'end of the lever. v

2. An upper window sash having a bolt socket in its meeting rail; a lower sash with a passageway through its meeting rail, a slidable bolt extending through said passageway; a lever 011 the lower meeting rail for retracting the bolt the latter being adjustably connected with the lever; and a spring for automatically throwing the bolt.

8. An upper window sash having a bolt socket in its meeting rail, a lower sash with a passageway through its meeting rail; a slidable bolt extending through said passageway, and having notches in its outer end; a lever on the lower meeting rail for retracting the bolt; said lever having a slotted end adjustably engaging the bolt; and a spring for automatically throwing the bolt.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

ROBERT HENRY.
